When I return home, I find that my once-responsible and beautiful older sister KANA has divorced and become an unruly unemployed shut-in. With our mother away, she flaunts her breasts and notices my erection. Years of playing erotic games have left her desperately horny, and she becomes fascinated by how much her brother has grown. Her sense of boundaries collapses as she turns my cock into her masturbation toy. I know it is wrong, but the sight of her taking me deep makes me lose control and creampie her. From then on, we fuck repeatedly until morning in the living room, the bathroom and her bedroom.
